Include snakeyaml into final jar, delete compat layers (#4070)

Snakeyaml is an untypical library which most Via platforms don't have and also broke in the past with V2, having it directly in the jar like Gson cleans up the build scripts massively, reduces the build time and also doesn't break in the future if they release V3 or any other breaking changes.
